APPARATUS FOR DRAWING AND CHARGING BLOOMS.

SPECIFICATION forming part of Letters-Patent No. 437,819, dated October'7, 1890.

To all whom it may concern-.-

Be it known that I, JOSEPH MORGAN, Jr., a citizen of the United States,residing at J ohnstown, in the county of Oambria and State ofPennsylvania, have invented certain new and useful Improvements inApparatus for Drawing and Charging Blooms; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Finished bars of iron or steel are generally rolled or hammered from abloom, billet, or pile. Previous to rolling, these blooms have to beheated in a furnace, and the furnaces in general use for this purposeare well known and need not be described.

Various methods have been used for charging blooms into and for drawingthem from the furnace. I use the term bloom in its generic sense. It maybe a bloom, a billet, a pile, or any form of material to be heated orhandled when hot.

One of the old methods of charging and drawing is as follows: A chargingpeel or tool of iron shaped like a paddle or oar and provided with across-handle at its end is placed with its blade resting on thefore-plate of the furnace-door, the handle being held by one or moreworkmen. The bloom is then placed upon it by other workmen, when byaunited. effort the peel with bloom on it is pushed into the furnace,after which the peel is withdrawn and the operation is repeated. Drawingthese blooms from the furnace is accomplished in an equally laboriousmanner by the use of tongs in the hands of the workmen. This method hasbeen modified and made more easy by suspending the charging-peel on aswinging crane, the drawing being done by the use of a tongs actuated bysteam or other power, these tongs merely pulling the bloom from thefurnace and allowing it to drop on a buggy under the door.

Various other devices have been used for charging and drawing blooms;but most of them are cumbersome, liable to accident, or laborious inoperation.

The object of my invention is to provide an apparatus for chargingblooms into and d ra wing them from a heating-furnace in an economical,speedy,convenient, and non-laborious manner.

A general description of my charging and drawing machine is as follows:The apparatus described below is for use in connection with a furnacehaving a horizontal bed. Above the furnace-doors and parallel to thefurnace front is an elevated track supported on posts and girders. Infront of the furnace is another track parallel to the first andsimilarly supported. On these tracks is supported a traveling cranewhose frame is made of girders. This traveler has four wl1eels-t\\*o oneach track-one pair being driven in either direction bya pair ofreversing-engines, these engines being carried on the traveler. Thistraveler has on it a track at rightangles to the axis of the furnace andto the travelertrack. This track on the traveler carries a trolleyresting on four wheels and capable of motion backward or forward.

On the shaft of the engine before mentioned is a sheave for wire rope,and at the opposite side of thetraveler is a similar sheave on a shaftparallel to the engine-shaft. The sheave on the engine-shaft is throwninto or out of motion by a clutch. A number of wire ropes run over thesetwo sheaves, their ends being fastened to the trolley. This trolley maythus be moved backward or forward on its track by the engine at the willof the operator controlling the reversing-lever of the engine and theclutch-lever. This trolley may also be moved by a long pneumatic plungerworking in a double-acting cylinder fixed at one end of the traveler,its motion being controlled by a valve with a convenient lever. Inpractice, the use of this last device is found to be better than the useof the wire rope for moving the trolley. This trolley has a flatrectangular top with stiffening-ribs on its lower sides. Forminga partof and extending vertically downward from the bottom of thistrolley-frame is a cylindrical tube with curved ribs uniting it to thetop part of the trolley-frame, these ribs acting as stiffeners. Thiscylindrical tube is bored to receive a vertical shaft. This shaft has onits upper end a collar to prevent it from moving downward. This collartakes its bearing against a suitable shoulder on the 25 from the end.

trolley-frame. This vertical shaft extends above the frame and carriesfirmly attached a crank or rocker arm. This crank is connected by ashort connecting-rod with the piston of a double-acting pneumaticcylinder carried on top of the trolley. This cylinder 1 call theturning-cylinder. The motion of the piston is controlled by a suitablevalve connected with a hand-lever. The vertical 1o shaft is thus capableof partial revolution about its axis.

At the lower end of the vertical shaft above referred to is a steelcasting or forgin g bored out to receive the end of the shaft, to whichit is firmly attached. This casting has on one side an arm which isinclined downward, and at the opposite side it has a fiat face, againstwhich is attached a double-acting pneumatic cylinder with a trunk. ThisI call the lifting-cylinder. Pivoted at thebottom 0 piston of thelifting-cylinder will cause the end of the long arm of the charging-barto describe a vertical arc, the direction of its motion being oppositeto that of the piston, and its motion will be greater than that of 3 5the piston, depending upon the relative length of its arms.

The casting at the lower end of the vertical shaft before mentioned hasanother vertical face at right angles to the one to which thelifting-cylinder is attached. Against this face is attached anothervertical pneumatic cylinder with a trunk and pitman. This cylinder Icall the gripping-cylinder. This pitman is connected with a short crankkeyed to a 5 shaft called a gripping-shaft, which is held inbearingsalong the side of the chargingbar before mentioned. This shaft extendsthe length of the bar and has at its far end a heavy crank, which crankforms the movable side of the jaw which grips the bloom. Opposite tothis movable jaw isasimilar stationary one attached to the end of thecharging-bar, both jaws being fitted with removable bits or points ofhard steel. Theinside lines of these jaws when closed-form an opensquare with the opening downward, and having on its sides near thebottom two projecting points. It will thus be seen that the motion ofthe piston of the gripping-cylinder may be made to cause thegripping-jaws to open or close, as

may be desired. That part of the chargingbar which is subjected to theaction of heat during operation is cooled by causing water to circulatethrough properly-formed ducts fashioned within it.

In connection with this charging and drawing machme I use a trackrunning on the working-level in front of the furnace, and

upon which run the cars which deliver blooms to be charged.

Placed alongside of the outer posts carrying the traveler-track is aseries of driven rollers which extend to the roll-train which is to rollthe bloom. These rollers are carried inasuitable frame having boxes toreceive the roller shafts and bearings, which hold a drivingshaft, whichlatter is fitted with a number of bevel gear-wheels, which mesh withsimilar wheels on the rollershafts. This shaft may be driven bya pair ofreversing engines or in any suitable manner. Above the frame carryingthe rollers and attached to it are two angle-bars so placed as toprevent the traveling bloom from leaving the rollers in its passage tothe roll-train. These an gle-bars serve also as a track upon which runsabosh on wheels, the bosh being filled with water with which to cool offthe end of the charging-bar. drawing and charging apparatus can grip abloom on a buggy or car, lift it up, carry it to a position in front ofanyone of the furnacedoors, swing it around, insert it in the furnace,and lower and leave it in a proper place on the furnace-bed. All this isdone without manual labor other than that necessary to move the leverscontrolling the various motions. The bloom is withdrawn by areversal ofthe above operation and is deposited on the rollers, which carry itquickly to the first pass of the rolls in the roll-train.

Having given this general description 0 my invention,I will now, to makemy invention more clear, refer to the annexed ten sheets of drawings,which form a part of this specification, and in which like figures referto like parts.

a vertical section of the trolley, taken at right angles to thedirection of its 1notion,showing traveler-frame, trolley-track, andgrippingcylinder in vertical section, and vertical shaft,trolley-wheels, and air pipes and joints in elevation. Fig. 9 is abottom plan of lifting and gripping cylinders and their attach ments,and showing section of vertical shaft and its lower roller-bearing. Fig.10 is a cross-section taken at right angles to vertical shaft throughlifting and gripping cylinders, showing inclined arm and pivot forcharging-bar in bottom plan. Figs. 11 and 1.2 are elevations showingdetails of clutch, clutch-levers, and fork for throwing into and out ofgear the parts which cause the traveler and trolley movements. Fig. 13isa back end elevation of grippingcylinder and its attachments. Fig. It isan end elevation showing lower end of trunk and pitman ofgrippingcylinder and its attachments, and showing charging-bar incrosssection. Fig. 15 shows lower end of trunk of the gripping-cylinderand the universal joint in vertical cross-section and charging-bar inend elevation. Figs. 16 and 17 show crosssection of a bloom in thegripping-jaws of the machine. Fig. 18 is a plan showing inner end ofcharging-bar with gripping-shaft and its bearing and crank-arm, togetherwith details of water-cooling pipes.

In the different figures, A represents the cross-section of a horizontalheating-furnace with the door A.

B is a bloom to be charged into or being drawn from the furnace Athrough the doorA'. ct is the charging-floor of the furnace A.

O is a post for carrying the girder O, the corresponding girder 0 beingcarried by similar posts or by the furnace-frame.

I) is a traveler-frame having the wheels X X X X, which carry it and runon the track, which is supported by the girders O O.

E is a pair of reversing-engines carried on the traveler D. This cngi nehas a driving-pinion J on its shaft which meshes with and drives thespur-wheel K, which spur-wheel. is attached to the shaft- L This shaft Lruns in bearings supported by the traveler D and communicates motion tothe traveler-wheels X X by means of the clutch U U and the bevel-gears VV V V, the last bevel-wheel being attached to the axle \V of the wheelsX X.

c is a connecting'rod for moving the rockerarm 0, which moves the clutchU.

The engines E are handled by the lever (7, (shown in Figs. and 4,) andby a reversing lever in the usual way. This engine E thus supplies powerto move the traveler D backward or forward on its track, at the will ofthe operator.

I is a trolley-frame having the whcclsff f"f', which run on the rails ZZ, which rails are supported by that part of the traveler-frame marked Yin Fig. 2. This trolley I has a flat top (shown in plans in Fig. 5) anda hollow cylinder projecting vertically downward therefrom, as shown inelevation and section in Figs. 7 and 8. This cylinder is bored out toreceive the vertical shaft k to the upper end of which is fastened thecrank j. This vertical shaft has a plain bearing near its top and aroller-bearing near its bottom in the cylindrical part of thetrolleyframe, as shown in Figs. 7, S, and 9.

On the top of the trolley-table is a doubleacting pneumatic cylinder 71having a piston h, piston-rod h', and valve 1.

m and m are hand-levers attached to the shaft 771,", at the upper end ofwhich is the rock er-arm m, which moves the valve Z of theturning-cylinder h. Attached to thepiston-rod h' is the head i, fastenedby the key 1''. The

outer end of the piston-rod h works in the 7 bearing 1'.

The head t" is connected with one end of the short connecting-rod i,which latter is connected by a crank-pin to the crank J. Thus a motionbackward or forward of the piston It will cause a partial revolution ofthe crank J and the shaftk attached to it.

As shown in Figs. 1, 2, 3, and 4c, the engineshaft L carries thewire-rope sheave K, which runs freely 011 the shaft until thrown intogear by the clutch T T, which is moved by the lever 1), shaft 1), rod12', and lever with fork b.

As shown in Fig. 1, there is on the opposite side of the traveleranother wire-rope sheave K in line with the sheave K. Over these twosheaves passes a number of wire ropes, indicated 011 the drawings by abroken line. The ends of these wire ropes are fastened to thetrolley-frame I by eye-bolts on opposite sides of the frame. It willthus be seen that the revolution of the sheave K will cause the trolleyto move on its track in either direction at the will of the operator incharge of the clutch-lever b and the engine-levers.

I do not limit myself to the use of the arrangement of wire ropes andsheaves for moving the trolley, as it may be moved by the action of apneumatic piston-rod havinga piston moving in a double-acting cylinderattached to the traveler-frame, the motion of this piston beingcontrolled by a convenient lever connected with the valve of thecylinder. The manner in which this can be done may be readily seen by askilled mechanic.

The vertical shaft k has firmly fastened to its lower end the steelcasting 7c. The body of this casting is square in form, having twovertical plane faces at right angles. Against these faces are attachedthe lifting-cylinder G and the gripping-cylinder F. On the side of thecasting opposite the lifting-cylinder is a short heave-arm inclineddownward. The lower part of this arm has a hole, into which fits the pin70 which holds the forging k. This latter is attached to thecharging-bar M. The bolt 7c" and the forging k together form a jointabout which the bar M may make a partial revolution in a vertical plane.

The lifting-cylinder G has a piston o and a trunk 0. In this trunk worksthe pitman 0", which grasps at its lower end the pin 0'',

which pin is attached to theend of the charging-bar M, by means of theforging p. This lifting-cylinder is double-acting, and has a valve whichcan be moved by a motion of the lever r, causing the piston to move upor down at the will of the operator.

F is a double-acting cylinder called the gripping-cylinder. It has apiston q, with a trunk, within which works the pitman g which isattached to the rocker-arm g, by means of the universal joint 1;. Thisgripping-cylinder has a valve which is moved by the lever r, and isdouble-acting.

The gripping-bar M is rectangular in section, and has at its end acasting or forging H firmly bolted to it. Along this bar M, parallel toit and supported by it, is a shaft N, to the inner end of which isfirmly attached the rocker-arm q, before referred to. The inner end ofthis shaft N is held in the bearing 25, which is attached to the bar M,while the outer end is carried in bearings in the part H. Firmlyattached to the outer end of the shaft N, opposite to the stationaryjawH, is the movable jaw H. These jaws have removable bits or points marked8 s.

It will be seen that an upward motion of the piston q of thegripping-cylinder F will open the jaw formed by H and H, while adownward motion will close the jaw.

The charging-bar M is bored out to receive the cooling-pipe a, while theshaft N is similarly fitted with the cooling-pipe 111. These pipessupply water for circulation in the interior of bar M and the shaft N,in order to prevent these parts from becoming overheated in thefurnaces.

The various cylinders on the machine are supplied with steam orcompressed air by the main pipe R,with branches S and others havingsuitable swing-joints to allow for the motion of the different parts ofthe apparatus.

ThepipesS S are supported by arod clamped fast to the upper one, the topof the rod having a'wheel which moves on and is supported by a lightoverhead circular track. for the cooling-pipes u and u is conveyed tothem by a hose from a stationary hydrant near the post 0. (Shown on Fig.1.) This hose is supported overhead at various points along its lengthby U-shaped carriers, which have wheels running along a track at theoutside of the girder 0.

Referring now to Fig. 1, O is a pair of reversing-engines with a drivingpower on the engine-shaft. This pinion meshes with and drives thespur-wheel P, which is attached to a long shaft which has on it a numberof bevel-wheels. Each of the bevel-wheels on this long shaft drives asimilar bevel-wheel attached to the shaft of a roller held in a longframe. One of these rollers is shown in end elevation at Q. This line ofrollers extends from the heating-furnaces to the feedtable of aroll-train, or if the driven rollers are higher than the feed-tablethere may be an inclined way having plain rollers connect,-

Water ing with the driven rollers at its top andwith the feed-table ofthe roll-train at its bottom. On top of the long frame carrying thedriven 7o rollers are two angles 0:00, which serve as guides to keep thebloom in place while being transported on the rollers to the roll-train.These angles also serve as a track upon which runs a water-bosh onwheels. This bosh w is used to cool off the heated end of thecharging-bar M during the course of operations.

The operation of my bloom charging and drawing machine is as follows: Acar of blooms is brought into position in front of the furnace, as shownin Fig. 1. The gripping cnd of the charging-bar is raised and thetraveler is caused to move so as to bring the gripping-jaws directlyover a bloom. The open jaws are .now made to descend and grasp a bloom,which is then lifted clear from the car. The traveler is then made tomove, if necessary, so as to bring the bloom in front of thefurnacedoor, and the charging-bar is swung at the same time on itsvertical shaft in such a way as to bringit at right angles to the axesof thefurnace. The trolley is then made to move forward, carrying withit the charging-bar and the bloom until the latter is over its properposition on the furnace-bed. The jaw end of the charging-bar is thenlowered, and as soon as the bloom touches the furnace-bottom thegripping-jaws are opened, thus depositing the bloom in place. The jawend of the bar may then be raised and the bar withdrawn, when it isready for another operation. W

The process of drawing is the reverse of the above, with the exceptionthat after being withdrawn from the furnace the bloom is swung around ina horizontal direction and deposited on the carrying-rollers Q, whichconvey it tothe proper place for subsequent operations.
